1-14. (canceled)
A process for producing a conductive paper web comprising:
- depositing an aqueous suspension of fibers onto a porous forming surface to form a wet web, the aqueous suspension of fibers comprising pulp fibers and conductive fibers, the conductive fibers comprising carbon fibers, the carbon fibers being present in the wet web in an amount of at least about 2% by weight based upon the total fiber weight;
- placing the wet web onto a surface of a rotating heated Yankee dryer drum and drying the web;
- and
- removing the dried web from the surface of the Yankee dryer drum without creping the web.
